About ATI Inc.

Globally, ATI Inc. stands as a premier manufacturer and supplier of specialized materials and complex components. The enterprise's operations are strategically divided into two primary divisions: High Performance Materials & Components (HPMC) and Advanced Alloys & Solutions (AA&S). The HPMC segment is responsible for creating a diverse range of advanced substances, including titanium and its numerous alloys, nickel- and cobalt-based alloys (such as superalloys), sophisticated powdered alloys, and other distinctive specialty materials. These are offered in elongated product forms like ingots, billets, bars, rods, wires, various structural shapes, rectangular sections, and seamless tubing. Additionally, this division engineers precision forgings, finished components, and custom-machined parts, primarily catering to the aerospace, defense, medical, and energy industries. In contrast, the AA&S segment focuses on producing zirconium and its associated alloys, which include hafnium and niobium, alongside nickel-based alloys, titanium and its specific alloys, and other unique high-performance alloys. These are commonly supplied as plates, sheets, and meticulously rolled strip products. This segment further extends its services to include hot-rolling conversion for materials like carbon steel and titanium products. The offerings from AA&S find critical applications across the energy, aerospace and defense, automotive, and electronics sectors. Formerly known as Allegheny Technologies Incorporated, ATI Inc. was established in 1960 and currently maintains its corporate headquarters in Dallas, Texas.
